The XScopes

The XScopes are a combination of three electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator and a protocol sniffer. The XScopes can also be used as development boards for the AVR XMEGA microcontroller. The Xprotolab and Xminilab can be plugged directly on a breadboard.

Main Features:

• Mixed Signal Oscilloscope: Simultaneous sampling of 2 analog and 8 digital signals.
• Arbitrary Waveform Generator with advanced sweep options on all the wave parameters.
• Protocol Sniffer: SPI, I²C, UART
• Advanced Triggering System: Normal / Single / Auto / Free, with many trigger modes; adjustable trigger level, and ability to view signals prior to the trigger.
• Meter Mode: VDC, VPP and Frequency readout.
• XY Mode: For plotting Lissajous figures, V/I curves or checking the phase difference between two waveforms.
• Spectrum Analyzer with different windowing options and selectable vertical log and IQ visualization.
• Channel Math: add, multiply, invert, and average.
• Horizontal and Vertical Cursors with automatic waveform measurements, and waveform references.
